Background
The nonlinear optical crystal material refers to a crystal material having a frequency conversion effect, an electro-optic effect, a photorefractive effect and the like. When light propagates through the crystal, the optical electric field interacts with the crystal to cause electrical polarization of the crystal, thereby generating a polarization field, which in turn generates radiation light. When the light intensity is not large, the polarization field intensity and the photoelectric field intensity are in a linear relation, and when the laser light intensity is small, the second-order nonlinear term of the polarization coefficient cannot be ignored. Under the action of the secondary nonlinear coefficient, the radiation light generated by the nonlinear polarization field is not the frequency of the original incident light any more, and the wavelength is changed, so that the laser frequency conversion under the nonlinear optical effect can be realized.
